The problem for book collectors these days is that once a book goes into paperback production, the harcover is almost impossible to find. Idle Time Books, now moved into a bigger location on 18th Street, has a tremdous back catalog of hardcovers and softcovers. The prices are pretty reasonable, too. I'm also always impressed by the staff's familiarity with their wares. I went in looking for an obscure Douglas Adams book and the CSR pinpointed the exact location immediately. Insane!
